Material Index help

[Racleborg]

I would like to be able to tweak a material's colour and or glossiness during or after the render. I know how to do this in Cycles but can't seem to get the Material Index to show up in the Render layers input (like the light groups do) in lux?

I'm probably missing the obvious!

Thank you

- Assign a material index in the material output node
- Enable the Material ID AOV
- Use an "ID Mask" node to split the material ID AOV into the separate masks for various IDs: https://docs.blender.org/manual/en/dev/ ... _mask.html

Great.

Thank you.
